The power2max Type S Rotor 3D+ power meter only is one of our most popular models. It’s the ideal choice if you already have a set of Rotor 3D+, 3DF, 3D30, Rotor Flow or Rotor 2D crank sets. The power meter replaces the spider of your existing cranks, making for a convenient and easy upgrade. The Rotor 3D+ and 3DF cranks are often installed on Cervélo bikes, such as the P5, P3, S5, or R5.
Type S is the second generation of power2max power meters and improves on the already outstanding features of power2max Classic. Of course it’s as precise, easy to use, robust and reliable as the Classic power meter. On top of that it’s 70 to 80 grams lighter than the power2max Classic and offers even greater compatibility: it’s not only fully compatible with compact aero chain rings, it is also more compatible with BB386EVO frames.
Using a power2max Type S is as easy as it gets: once it’s installed on your cranks and paired with your computer, all you do is start riding. No messing about with complicated calibration procedures, frame magnets, or worrying that the power meter reads wrong because you changed chain rings – all that is taken care of. When the time comes to change the battery after about 400 hours of riding you can do it in the comfort of your home.
